* Parts Sourcing: Many parts for GM vehicles come from various global sources, not just the US. Even vehicles assembled in the US will utilize many foreign-made components.
* Assembly Location: GM assembles vehicles in multiple countries, including the US, Mexico, Canada, and others. The percentage of vehicles assembled in the US varies by model and year.
* Definition of "Made in America": There's no universally agreed-upon definition. Does it mean assembly only? A certain percentage of US-made parts? A certain value of US content?
To get a precise percentage, you'd need to specify your definition of "made in America" and analyze detailed GM production data, which isn't publicly released in that specific form. News articles and reports sometimes offer estimates, but these will vary depending on their methodology and the year in question.
